Insert a capacitor between the Vo and GND pins in order to prevent output oscillation.
The capacitance may vary greatly with temperature changes, thus making it impossible to completely prevent oscillation.
Therefore, use a tantalum aluminum electrolytic capacitor with a low ESR (Equivalent Serial Resistance). The output will
oscillate if the ESR is too high or too low, so refer to the ESR characteristics in Fig. 20 and operate the IC within the stable
region. Use a capacitor within a capacitance between 22F and 1,000F.
 Vcc pin
 GND pin
 CTL pin
Insert a capacitor (0.33 F approx.) between VCC and GND.
The capacitance will vary depending on the application.
Use a suitable capacitance and implement designs with sufficient margins.
Verify that there is no potential difference between the ground of the application board and the IC.
If there is a potential difference, the set voltage will not be output accurately, resulting in unstable IC operation.
Therefore, lower the impedance by designing the ground pattern as wide and as short as possible.
The CTL pin turns on at an operating power supply voltage of 2.0 V or higher and turns off at 0.8 V or lower.
There is no particular order when turning the power supply and CTL pins on or off.
